I installed wxdev in my win7 64bits and tried to execute it I got a single execution that asked to autogenerate set or what ever it does in the first time. After that I can not open it again at all, it raises a gpf I believe and it exits. So my question is simple, is wxDev actively developed or not?

I am afraid wxDevC++ has not been developed since couple years. Below is a link to another post with similar conclusion. I can only advise that wxDevC++ version 7.3.1.3 runs fine on Win XP x32 and Win 8.1 x64 (from my experience).viewtopic.php?f=28&t=41928&p=169597&hilit=wxDev#p169597
